No country is doing enough to tackle rising emissions, the UN’s climate chief Christiana Figueres has said.
She welcomed President Obama’s recent policy announcements on renewable energy and efficiency but said governments were still falling short.
“Finally the United States is putting out a menu of very concrete measures,” said Figueres.
“But I think the fact remains that compared to what the science demands…no country is doing enough,” she told Reuters at a meeting of climate activists in Istanbul.
Scientists have determined that warming beyond 2°C would be dangerous with governments agreeing to adopt this target during the Copenhagen UN climate negotiations in 2009.
Figueres was pleased to have a shift in stance from the US which has struggled to make strong climate commitments in the face of domestic hostility from Republicans.
She warned that it was important for the US to now follow through in its promises.
“I do think that an energy czar in the White House would be extraordinarily helpful,” she said. “There has to be someone at a high level in the White House that can actually coordinate all of this and ensure that it gets done.”
